Keck I and II at Mauna Kea, Hawaii

Keck is so enormous, it is impossible to fit one of the telescopes into a single picture. This is the secondary mirror and the truss cage from the dec axis and above.

Looking down on part of the primary mirror from the dec axis. Note the door in the far side of the frame (shown for scale).
